Abstract

Cette invention concerne un outil en métal dur à régions multiples (10). L'outil comprend un corps en métal dur (12) avec composant en particules dures et liant ; un corps supplémentaire comprenant un corps en métal dur (14) avec composant en particules dures et liant ; un corps en métal et un corps en céramique ; un couche limite sensiblement discontinue, sans gradient, entre le corps en métal dur et le corps supplémentaire ; et une surface d'appariement (16) entre le corps en métal dur et le corps supplémentaire. Selon un mode de réalisation préféré, les composants faits de particules dures sont constitués par un carbure, tel qu'un carbure de tungstène. Selon ce mode préféré, la surface d'appariement (16) comprend une partie mâle (20) sur l'un des corps et une partie femelle correspondante (22) sur l'un des autres corps. La surface d'appariement (16) est symétrique ou asymétrique. Dans le mode de réalisation préféré, elle est axialement symétrique, sous forme d'une alvéole par exemple. Cette surface peut présenter par ailleurs des caractéristiques d'appariement à la au niveau micro et au niveau macro.
